Tasmanian Detailed Gravity (P198854), gravity point data

Gravity data measures small changes in gravity due to changes in the density of rocks beneath the Earth's surface. The data collected are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose. This Tasmanian Detailed Gravity (P198854) contains a total of 417 point data values acquired at a spacing between 50 and 200 metres. The data is located in TAS and were acquired in 1988, under project No. 198854 for None.

重力数据可用于测量地球表层下方岩石密度变化所引发的微小重力场变化。所采集的原始数据将通过标准方法进行处理，以确保所记录的重力响应仅由地下岩石引起。经处理后生成的数据集可通过解译，用以揭示地下地质构造特征。GA地球物理学家会对处理后的数据开展质量核查，以确保GA发布的最终数据符合使用要求。本数据集为塔斯马尼亚详细重力数据集（Tasmanian Detailed Gravity, P198854），共计包含417个测点数据，测点间距介于50米至200米之间。该数据集采集于塔斯马尼亚州（TAS）境内，采集工作于1988年完成，对应项目编号为198854，委托方信息未标注。
